, ,To all @v7-waa it may concern .1. e l Beit'jlmoivn that'I, CHARLES F. Massei', a

Hcn'

citizen o 'the United States, and resident of Chicago, in the countyof Cook and State of Illinois, have` invented certain new and use ful A Improvements in Lamp-Supporting Structures, `of which the following is @a specification.

Myinvention relates .to 'lamp supporting structures,Av particularly' to structures used for -A street illuminating purposes. Such structures usually comprise a post from which extend lamp supporting brackets.

Among the ,important objects of my. invention are to provide an arrangement in .which a lamp supporting frame is detachable with reference to its supporting post so that the post and frame can be more readily built lip/of concrete or other cementitious material andmore readily shipped; to' provide simplied means' whereby the lampsupplc'irting -frame may be quickly and readily appliedv to the post when the post is set up forservi'e; toprovide asimplified arported in upright position or in depending position; to provide improved construction and arrangement Winch will-allow connections to be readily made between main current supply conductors running through the postvand leads extending througlithe supporting frame to--the lamps; and in general 'to provide more efficient and desirable construction'and arrangement in lamp supporting'sti'iictures. f

In the accompanying drawings Figure 1 is an .elevational view of a lamp supporting structure, with some of the lamp structures removed; Fig. 2 is a plan View with some of the lamp structures removed; Fig. 3 is a sectional View talen Ion plane 3-3, Fig. l;

.Fig.. 4 is a. sectional view taken on plane 1 -4, Fig. 2, and Fig. V5 is an elevational View o f. the upper end of the post with the lamp supporting structure removed. 'Referring to the drawings a post l-O is built up of 'concrete and has an enlarged base Hand an enlarged head '12, there. be-

. inga polygonal upward extension 13' from tlieliead for receiving 'a lamp supporting structure. This lamp supporting structure.

comprises aV hub 14 and armslextending' laterally therefrom; The passageway 16- through the hub -is polygonal to receive the extension l?) so that the hub' may be slipped downwardly` about the extension and seat againstthe head lf2 of the post. Extending Y through each arux is a pipe 1T. the inner ends of these pipes terminating at the hub passageway lt and the outer ends'terminating, :s shown in the figures. at the upper sides of the ends ot' the arms. The ends ot the arms serveto support lamp holding devices 1S which are secured to the arms iu register with the outlets ot' the ducts l?. rlhe holdei's l8 will su'pp'ort each a lamp 19. and if desired. a globe Q0. VIn the arrangement shown the lamp supporting frame has been vapplied to .support the lamp structures in upright position but it is ev'dent that this frame can be reversed so that .the lamp structures will be supported in depending position, as shown in dotted lines. V In either position the trame receives the'extension 13 and seats securelir against the head l2.'

A conduit pipe 2l extends through the post and receives the current supply conductors which connect with the street mains in any desired manner. .is shown. across pipe QQ extends through the base of the post -and is threaded at its protruding ends for insertion in the street duct or pipe. In order.

that connections nizriY readil)v be made between the. main supply conductors 23 and leadsQBf extending through the pipes 1T to the lamp structures. theextension 13 is hollow to provide a compartment Bfl and lateral passageways Q3. which passageways register with the inner ends of the pipes 17. lVhen the lamp supportingframe is set on the post the ends of the main suppl;7 conductors and the leads can be made in the compartment Q4 or'these ends can be extended out through the upper end ofthe hollow extension and made outside ofthe post, and then put backV into the compartment 24. A center light 9.6 may be provided vwith its holder 27 seated on the end of the A terial and the pipes 17 besides acting z" conduits for the leads to the illuminante lalso serve to reinforce the concrete. Likewise the pipe 21 .which conveys the currentsupply conductors from the base of the post to the .compartment 24C WilLserve to reinforce the concrete. ing material `may of course be provided.

By having the lamp supporting vstructuieA detachable, shipmentv can be more readily made and furthermore when the post is installed the lamp supporting framecanbe easily applied in position either to support the lamps upright or in position to support the lamps in depending arrangement'.v No extraneous securing means arenecessary 'as the hub of the supporting frame snugly receives the extension Q4 and securely seats onl the head of the post;

. l. do not of course desire to he limited to the exact construction and arrangement shown and described except as specified in the claims which are as` follows:

l. In a lamp supporting structure.` the combination of a post having a reduced neck extending upwardly therefrom and 4having a shoulder at the base'of the neck, said neck being polygonal and-hollow, and its outer facesV being vertical, al huh having a Vertical polygonal bore for slipping over said neck to engage with either end'against said shouland supporting light ixtures at their ends, passageways through the sides of said neck 'to the interiorfthereof, and ducts through said hub and arms extending from the light Other or additional' i'einforc- 1913. der, arms extending radially from. said h-ub f filatures and .terminating at" Ways.
